Deflection of Laminated Beams

A theory is developed to determine the deflection of a beam composed of two or more laminations and riveted or fixed at certain points along the beam. The laminations can be of different sizes and materials but must be long in comparison with the cross-sectional dimensions of the beam. Although the problem investigated is based on only two laminations, the same approach can be used to provide for any number of laminations. The final result is in a form such that particular problems can be solved in a manner similar to the area-moment method. It is shown that for two laminations joined at an infinite number of points the problem reduces to that of a simple beam. Two different cases of simply supported beams were tested and the satisfactory results are presented.
